Can inflationary models of cosmic perturbations evade the secondary oscillation test?
Alex Lewin, Andreas Albrecht
We consider the consequences of an observed Cosmic Microwave Background (CMB) temperature anisotropy spectrum containing no secondary oscillations. While such a spectrum is general…

A new statistic for picking out Non-Gaussianity in the CMB
Alex Lewin, Andreas Albrecht, Joao Magueijo
In this paper we propose a new statistic capable of detecting non-Gaussianity in the CMB. The statistic is defined in Fourier space, and therefore naturally separates angular scale…

Non-Gaussian spectra and the search for cosmic strings
Joao Magueijo, Alex Lewin
We present a new tool for relating theory and experiment suited for non-Gaussian theories: non-Gaussian spectra. It does for non-Gaussian theories what the angular power spectrum $…
